im am new to WoW (Classic) AddOn development. What i want to achieve with my first project is a simple target marking helper (skull, cross, ... marks) with a simple UI that has one button per mark with the icon on it.
I was wondering how to use InGame resources, but couldn't find a list of builtin resources. Then i found the Item icon IDs on wowhead which work great for icons of items and so on. But i cant find resource information about the target marking icons. Does anyone know these IDs or is there a complete resource list somewhere on the internet?
